rs6000: Add xxeval and vec_ternarylogic

Add the xxeval insn and access it via the vec_ternarylogic built-in
function.  As part of this, add support to the built-in function
infrastructure for functions that take four arguments.

[gcc]

	for __builtin_vec_xxeval.
	* config/rs6000/rs6000-call.c: Add handling of new macro
	RS6000_BUILTIN_4 in initialization of rs6000_builtin_info,
	bdesc0_arg, bdesc1_arg, bdesc2_arg, bdesc_3arg,
	bdesc_altivec_preds, bdesc_abs, and bdesc_htm arrays.
	(altivec_overloaded_builtins): Add definitions for
	FUTURE_BUILTIN_VEC_XXEVAL.
	(bdesc_4arg): New array.

	for unsigned QImode and unsigned HImode.
	(builtin_quaternary_function_type): New function.
	(rs6000_common_init_builtins): Add handling of quaternary
	operations.
	* config/rs6000/rs6000.h (RS6000_BTC_QUATERNARY): New defined
	constant.
	(RS6000_BTC_PREDICATE): Change value of constant.
	(RS6000_BTC_ABS): Likewise.
	(rs6000_builtins): Add support for new macro RS6000_BUILTIN_4.

	for a Future Architecture): Add description of vec_ternarylogic
	built-in function.
